Title: Air-fuel ratio controller of internal combustion engine
Inventor: YAMASHITA YUKIHIRO
IPC: F02D41/14
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To precisely control an air-fuel ratio to the theoretical fuel ratio even if the exhaust gas amount is changed, by suitably setting the speed of response of target air-fuel ratio feedback control according to the operating state of an internal combustion engine. SOLUTION: When the changes of the engine speed Ne and the intake air pressure PM are detected by an engine speed sensor 30 and an intake air pressure sensor 32, an air-fuel ratio controller controls the target air-fuel ratio correction amount so that the speed of response of target air-fuel ratio feedback control may be suitable. Therefore, the speed of response of target air-fuel ratio feedback control is suitably set, the high catalyst purifying factor is maintained, and the air-fuel ratio downstream a three-way catalyst 38 is approximately maintained to the theoretical air-fuel ratio. Therefore, the air-fuel ratio downstream the catalyst can be maintained to the theoretical air-fuel ratio even if the speed of response of the air-fuel ratio downstream the catalyst in relation to the air-fuel ratio upstream the catalyst is changed after the purifying capability of the three-way catalyst 38 is changed after the catalyst capacity per unit exhaust gas amount is changed, and exhaust of harmful components in exhaust gas can be restrained regardless of the operating state of an engine 10.

Abstract: PURPOSE: To obtain the subject compound useful as a synthetic lubricating agent or as a functional fluid by reacting an α-olefin monomer with a catalyst comprising boron trifluoride, a protic promoter and a polyether.  
     CONSTITUTION: An α-olefin oligomer is obtained by containing a 6-20C α-olefin monomer with a catalyst comprising boron trifluoride, a protic promoter and a polyether at 0-200°C and under atmospheric pressure, preferably at 20-65°C and under 5-100 psig.
